Improvement in vapor-burners



UNITED STATES PATENT OFFICE.

JOHN COOK, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF HIS RIGHT TO G. L.SMITH, OF SAME PLACE.

IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 120,627,dated November7, 1871.

To all whom it may concern:

Be it known that I, JOHN COOK, of the city, county, and State of NewYork, have invented certain Improvements in Vapor-Burners, of which thefollowing is a specification:

This invention relates to that class of burners used for the productionof light from very volatile hydrocarbons; and consists in thecombination and arrangement of various parts or devices as asupply-tube, provided with two lian ged disks near its upper end, andbetween which are holes to furnish carbon for heating them 5 also aslotted cap furnished with a screen of wire-gauze, all arrangedrelatively to each other, as hereafter described.

Figure l is an elevation of the burner-tip and anges. Fig. 2 is a bottomview of the upper flange, and shows the screen of wire-gauze in the tip.Fig. 3 is an elevation of the invention complete, with the step-valveall ready for connecting to the supply-tube. Fig. 4 is a verticalsection of Fig. 3.

The supply'tube is connected at A, Figs. 3 and 4, the inner end of whichis closed by the screw plunger or valve B, which is driven by a. keyinto the tube or against the end thereof, so as to stop any inward flowof the liquid toward the burner. Underneath said valve is a cup, O, forreceiving alcohol or some similar substance, which, when ignited, willheat the burner to such a degree as to generate gas at the disks andtips sufficiently to start the operation in complete working condition.From the chamber, between the end of the tube A and the valve B whenopen, a small hole, D, leads upward to a transverse opening, E, wherethe liquid can come in contact with the burning alcohol in the disk C,and give an additional supply of fuel to the flame for heating theburner. Immediately above said hole or outlet vE the burner proper isattached, it being fully represented at Fig. 1 5 and consists simply ofa tube, F, furnished near its upper end with two external disks, G andH, as shown in the drawing. To the upper disk H the slotted cap K may beattached 5 or it may be slipped on as a ferrule upon the upper end ofthe tube F, and thereby readily changed from a large to a small burner,and vice versa, as desired, without changin g the other parts. Throughsmall holes at O O, between the disks C and H, the heated vapor escapes,and, taking fire from the flame below, quickly heats the Atube F andexpands the vapor into an elastic gas by the time it reaches the cap K,when it will give a light equal to the choicest gas from coal. The underside of the external disk H is corrugated7 as shown at Figs. 1, 2, and3, to extend the heating-surface and to produce points from which thesoot will always be burnt,

so that the ilames from the jets O O will always come in contact withthe metal disk H. In the cap or tip K is placed a screen of wire-gauze,M, which serves as a retarder or check-valve to the flow of thevaporized liquid, so as to give asteady flow, the amount being greatlydue to the vari able sizes of the meshes in the gauze.

The vapor-burner, consisting of the tube F provided with disk G,corrugated disk H, holes O O, and slotted cap K having the wiregauzescreen M, all arranged in relation to each other, substantially as shownand described.

JOHN COOK.
